The Neurodegenerative Elderly Syndrome (NES) hypothesis: Alzheimer and Parkinson are two faces of the same disease.

Increasing evidence suggests that Alzheimer's disease (AD) and Parkinson's disease (PD) share monoamine and alpha-synuclein (αSyn) dysfunctions, often beginning years before clinical manifestations onset. The triggers for these impairments and the causes leading these early neurodegenerative processes to become AD or PD remain unclear. We address these issues by proposing a radically new perspective to frame AD and PD: they are different manifestations of one only disease we call "Neurodegenerative Elderly Syndrome (NES)".

Emotions Modulate Affordances-Related Motor Responses: A Priming Experiment.

Traditionally, research on affordances and emotions follows two separate routes. For the first time, this article explicitly links the two phenomena by investigating whether, in a discrimination task (artifact vs. natural object), the motivational states induced by emotional images can modulate affordances-related motor response elicited by dangerous and neutral graspable objects.

Motor Inhibition to Dangerous Objects: Electrophysiological Evidence for Task-dependent Aversive Affordances.

Previous work suggests that perception of an object automatically facilitates actions related to object grasping and manipulation. Recently, the notion of automaticity has been challenged by behavioral studies suggesting that dangerous objects elicit aversive affordances that interfere with encoding of an object's motor properties; however, related EEG studies have provided little support for these claims. We sought EEG evidence that would support the operation of an inhibitory mechanism that interferes with the motor encoding of dangerous objects, and we investigated whether such mechanism would be modulated by the perceived distance of an object and the goal of a given task.

Spinocerebellar ataxia: a critical review of cognitive and socio-cognitive deficits.

Purpose: The primary aim of this contribution is to provide a critical discussion on cognitive and sociocognitive implications of spinocerebellar ataxias (SCAs) subtypes. The term SCA refers to a group of neurodegenerative disorders that have been increasingly investigated in the last years, sharing the characteristic of progressive ataxia resulting from degeneration of cerebellum and its connections. In past decades only involvement of cerebellum in behaviour and timing has been investigated, bringing to the belief about its central role in timing of movement and sensation, particularly for short intervals of time.
